Randomized Controlled Trial Multicenter Study Comparative Study
Sagittal cervical alignment after cervical disc arthroplasty and anterior cervical discectomy and fusion: results of a prospective, randomized, controlled trial.
Radiographic results of a multicenter, prospective randomized study comparing 1-level cervical total disc replacement (TDR-C) with anterior cervical discectomy and fusion (ACDF). ⋯ In both TDR-C and ACDF, lordosis increased at the device-level, cranial adjacent level, and in total cervical lordosis, while lordosis decreased at the caudal adjacent level. Although ACDF facilitated a greater increase in device level lordosis (+1.25 degrees ) and less loss of lordosis at the caudal adjacent level compared with TDR-C (-0.39 degrees ), the clinical relevance of the small differences remain unknown.

Randomized Controlled Trial
Effect of epsilon aminocaproic acid on red-cell transfusion requirements in major spinal surgery.
: Randomized, placebo-controlled trial. ⋯ : The difference in total allogeneic RBC transfusions between the groups was not statistically significant. EACA was associated with a 30% (0.8 units) reduction in postoperative RBC transfusions and a 1-day reduction in ICU LOS, without an increased incidence of thromboembolic events. EACA may be considered for patients undergoing major spinal surgery. Larger studies are needed to evaluate the relationship between EACA and total RBC requirements.

Randomized Controlled Trial Comparative Study
Clinical study of low back pain and radicular pain pathways by using l2 spinal nerve root infiltration: a randomized, controlled, clinical trial.
Randomized control trial (RCT) for L2 spinal nerve infiltration (L2 block) in clinical cases. ⋯ The LBP and radicular pain pathways were likely interrupted by L2 block. An L2 block is useful in reducing LBP due to the disorders of L2 spinal nerve-innervated structures, such as the disc, facet joint, and sacroiliac joint. However, the therapeutic value of an L2 block may be occasionally insufficient to alleviate pain completely because of the short duration of its' effect.

Randomized Controlled Trial Multicenter Study
Neck/shoulder exercise for neck pain in air force helicopter pilots: a randomized controlled trial.
The study was a randomized, controlled trial with blinded outcome assessment. A 6-week intervention was followed up directly afterwards and after 12 months. ⋯ A supervised neck/shoulder exercise regimen was effective in reducing neck pain cases in air force helicopter pilots. This was supported by improvement in neck-flexor function postintervention in regimen members. However, no effect emerged for pain-related fear. General strength training before the intervention predicted reduction in prevalence of pain at follow-up.

Randomized Controlled Trial Comparative Study
Great expectations: really the novel predictor of outcome after spinal surgery?
Prospective study. ⋯ In this patient group, expectations of surgery were overly optimistic. Having one's expectations fulfilled was most important for a good outcome. The results emphasize the importance of assessing patient-orientated outcome in routine practice, and the factors that might influence it, such that realistic expectations can be established for patients before surgery.
